-is a full, clear, and exact description.

. The. special object'of this invention is to provide a metalllc underframe to receive a In carrying out the invention'center and i side sills of metal, f preferably pressed steel,

Ivs

are used, and these are connected by built-up bolsters, the sills running continuousl from end sill to end sill by preference and t e cen- -ter and side sills connected by transoms arranged sufficiently below their upper levels to receive wooden nailing-stringere, and

thereby preserve unim aired the carrying capacity of the body. Biagonal braces, also affording nailing-strips,are arranged between the bolsters andthe ends of the-car.

end sills may be of approved construction.

Reinforcing angle-pieces may be applied to the lower edges of the center sills. The side sills are provided with pressed or rolled me, tallic Z-bars to receive wooden nailing-strips, and thesenailing-strips are tied to the side lates by vertical tie-rods, whose heads or bolts are accessible from outside the car, all as I will proceed now more particularly to set forth and claim.

In the accompanying drawings, illustrating my invention, 1n the several figures of which like parts are similarly designated, Figure 1 is a top lan view of one end of the underi complete brace.

Fig. 6 is an elevationof the angle portion of the diagonal braces, with an end view thereof to the right.

All of these sills and diaphragms are Thebolsterd1aphragms 3 are hollowed out at 8 to afford clearance for the wheels, and the dia hragms 5 next the dp out in the peculiar manner indicated at 9, Fig. 3, in order to afford clearancev for the wheels in rounding a curve. The bolsters are provided with to cover-plates 10, riveted to the flanges of their diaphragms, and also with a bottom tieplate 11, which may extend no farther than the side bearings.

,The tops of the diaphragrns 5 and 6 are arranged at a lower level than the tops of the bolsters and center and side sills, and to them are bolted or otherwise secured the wooden nailing-stringers 12, the bOlster-diaphragms 3 having supporting-brackets 13 to receive the ends of said stringers. These strihgers are of a height to bring the top level of the underframe in one plane to receive the `flooring 14. As seen in Figs. 2, 4, and 5, the dia- Ehragms 4 and 7 between the center sills ave tops level with the tops of said sills, but

nai 'ng-stringers where necessary or desirable. y

. the also may be lowered to receive wooden By the lowering of the diaphragms as described it is possible to use a metallic underframe with wooden nailing-stringers without decreasing the load capacityl of the car.

Thev end sills v15 may be offapproved construction, and between them and the bolsters are ysimilar diagonal braces 16, composed of angle bars or strips T17, whose ends are secured toplates .18 and 19 below the top level of the sills and holsters, and .wooden nailingstrips 20 are bolted or otherwise. applied to these angle-bars, (see Figs. 1, 6, and 7,) which IOO raise the level to a uniform plane with the' Other dia onal braces 21 are secured to brackets 22 an 23', affixed, res ectively, tothe bolster side diaphragme and the center sills.

. The draft-ligging and the end sills may be Figs. 4 and 5,) with or without the reinforcof approved; construction andare herein shown as constructed in accordance withl well-known Pennsylvania Railway standards,

and hence need no description. 1

Y The center sills are provided with the reinforcing angle-bars 24, rolled or pressed, (see ing-stri s 25. These bars 24 are arranged to follow t e role of the sills from bolster to.

bolster an are riveted to them. The sidey sills have riveted to their top anges the vZ-bars 26, rolled or pressed, and

. these bars extend longitudinallyl of the sills and receive and support wooden stringere 27 lare bolted Aor otherwise secured to th\ d aredesigned to receive thewooden sided ofthe car. The ltop side plates 28: and these side stringers are connected by vertiv cally-arranged tie-rods 29, which pass through said plates,4 strips, and z-fblars, with their nuts arranged outside ofthe sills to admit of ready inspection andv easy" access if .they should have to be drawn u By the construction describe'it is possible to substitute a metallic or pressed-steel under?` fra-me for a wooden underframe in a wooden' car of the ordinary Master Car Builders standard.

f Instead of center sills continuous from end to end of the car 'and built-up bolsters I may use continuous bolsters and center sills extending from bolster to bolster in accordance withthe Pressed Steel Car Companys practice, and other variations also may be adopted without departingfrom the spirit and scope of my invention.`

vWhat I' claim is` 4 1. An underframe for cars', comprising essentially metallic longitudinal sills, diaphragms and holsters connecting flthem, the diaphragms between the holsters being ar! ranged at a level lower thanthat of the sills, wooden stringers applied to such dia- ..phragms, end sills, braces" applied between the end sills' and holsters below the level of. the holsters, and nailing-strips on said braces.

2. An underframe for cars, comprising essentially metallic longitudinal sills, diaphragms and bolsters connecting them,'-the diaphragms betweenjthe holsters being arranged at a levellower than that of thesills,

woo den stringers applied to such diaphragms,

metallic supports on the bolsters, for theendsof said stringers, end sills, braces applied between the vend sills andl bolsters below the level of the bolsters,"andnailing-strips on said braces. l
